| 摘要: |
| 基于三坐标测量的齿面网格节点偏差,经过三次B样条拟合得到法向偏差曲面,通过理论齿面与偏差曲面叠加构造斜齿实际齿面,推导了齿面法矢、齿面接触与边缘接触;编制了1套斜齿轮TCA程序,能够对各种实际齿面进行TCA仿真;通过齿向和三维修形算例验证了方法的正确性,为斜齿轮实际齿面接触分析提供了新方法。 |

| Abstract: |
| An approach application of gear meshing theory for calculating tooth working-surface contact, tooth edge contact and normal vector of helical gear real tooth surface is proposed to improve the transmission properties of drive gear.We represented the real tooth surface with a sum of two vector functions that determine the theoretical tooth surface and the deviation surface fitted by 3 B splines based on tooth surface mesh data from 3-dimentional co-ordinate measuring machine, and the normal vector of the deviation surface was deduced, having drawn up a set of calculation procedures, which simulate TCA of the helical gear tooth with various deviation surfaces.The model is proved to be correct when applied to gear drive of pinion with longitudinal and three-dimensional adding deviation surfaces, and provides a new method for TCA of real helical gear tooth surface. |
